LEONARD AUNES, OF CAMBRIDGE, MASSACHUSETTS.

sueaawarnn MACHINE.

Application filed July 24, 1914.

To @ZZ whom t may concern.'

Be it known that I, LEONARD AUNES, a citizen of the United States,residing at Cambridge, in the county of Middlesex and State ofMassachusetts, have invented new and useful Improvements in Sugar-WaferMachines, of which the following is a specilication.

The invention relates to an improvement in sugar' wafer machines, andparticularly to the combination with an ordinary type of such machine ofan automatic trimmer and receiver, whereby the material ordinarily eX-tending beyond the edges of the iron is trimmed subsequent to thebaking, and the completed wafer after trimming automatically deliveredto a receiver. In the ordinary use of these machines, it has beencustomary to cut the dough extending beyond the edges of the iron by theclosing of the iron and by the baking process, from such edges by anoperator standing in front of the machine, so that when the irons opento deliver the cake, it is trimmed ready for the icing machine and forthe usual sawing operation.

The present invention is designed with a view to eliminating the trimmeror operator heretofore performing this trimming operation and to providean automatic device which will effectively trim excess dough so as todeliver cakes from the irons in a properly trimmed and uniformcondition.

The invention in the preferredv form of details will be described in thefollowing specification, reference being had particularly to theacco-mpanying drawings, in which:

Figure 1 is a broken side elevation of the improved machine with thereceiver in position to receive a cake from the iron. Fig. 2 is asimilar view with the receiver in a delivery position, and showing thetrimmers in the final operation or trimming position. Fig. 3 is a planof the machine with the parts in position illustrated in Fig. 1. Fig. lis an end elevation of the machine showing the parts in their normalposition. Fig. 5 is a sectional view transversely of the machine andbeyond the trimmer operating mechanism.

Fig. 19 is a detail sectional viewof the receiver operating mechanism.

In the following description, I shall refer separately and independentlyto the trimming mechanism and to the receiving mechanism, the first ofwhich is designed to trim the excess dough from the baking irons, whilethe latter is to receive and pile the cakes after cooking and deliveryfrom said irons. The construction and also the illustration in the partsnot specifically herein referred to is of a conventional type of what isknown as sugar wafer machines, wherein dough is delivered to a series ofbaking irons connected in chain like form and adapted for travel onguide runways from a position where they are charged with the materialto and above the burners for cooking the material and to a positionwhere they are operated to deliver the baked material, means beingprovided for automatically opening the irons at their receiving anddelivery points.

For the purpose of the description, the main frame of the machine willbe generally designated as 1, which frame includes guide runways 2arranged in spaced relation and cooperating with which for appropriatetravel are the cooking irons 3 including upper and lower sections, thematerial being received, between the sections when the latter are open,the sections being subsequently closed andthe baking irons caused' totravel in such closed position above heaters as 4- for cooking thematerial, the sections of the irons being subsequently separated topermit the cooked cake to gravitate therefrom, the guide runways beingso arranged that in the delivery position the irons are elevated and ata downward and outward inclination to insure suchgravital delivery, asclearly shown in Fig. 1. Y

The trimming mechanism- As a preferred embodiment of the trimmingmecha-` msm, I provide an auxiliary base located trimmers and the latterreturns them to normal position. The lower ...end of the lever l11 is.secured upon the shaft 18 rotatably supported in the short Aupright 14rising from the base 5, while the :lever 12 is fulcrumed i intermediateits ends upon a shaft 15 rotatalbly mounted in the upright 6. A link 16is fulcrumed upon the shaft 15, being arranged between levers 11 andk12, the length being pivotally connected at its respective .ends aboveand below its fulcrum and the Vrespective levers, `as at 17 and 18. Anoperating arm 19 is secured upon the shaft 13 intermediate its ends sothat said arm turns with the shaft, the upper end i of the arm carryinga member Q0 on which is secured a gear segment 21, the latter beingarranged to mesh with the pinion 9 so that in the movement of the arm 19the shaft 8 is rotated.

rEhe lever 12 and arm 19 terminate in a plane below the shaft 13 and areconnected by a shaft 22 on which is secured an arm Q3. The arm extendsin parallel relation to the upper surface of the base and has at a point'l remote from the shaft 22 a lateral extension 24. This extension isconnected to a horizontal shaft 25 so as to permit independent rotativemovement of said shaft to prevent `independent longitudinal movementthereof with respect to said arm, the illustrated connection being the`slitting of the terminal of the arm and engagement of said slottedportion with the shaft between the collars 26. The shaft is slidablymounted in a hearing '27 risingvfrom the base, which bearing isprovided'with a lateral pin QS adapted to engage a spiral Islot or keyway 29 in the shaft, so that the shaft will be given a reciprocatoryrotary motion during its longitudinal reciprocation. Secured uprn theend of the shaft 25 is a transverse cutter including an arm 30 and to anupper end of which vis pivotalfly connected the lcutter arm 31, the arm30 being recessed in its upper portion to receive the lower end of thecutter arm, and the lower edge of said cutter arm and the cooperatingwall of the recess bein-g inclined as at 32, whereby swinging movementof .the cutter arm with relation to the arm 30 is permittedinv onedire'ction but `prevented `vin fthe-other, as will4 be'obvious'fromglig; 17. Aspring 33.6011-- nects the arm 30 and cutter armto normally hold the members in alined position. rl`he upper end of thecutter arm is provided with a cutting element 3l of U-forin having sideportions 35 of spring type and normally spaced .from the side portionsof the arm, each of said side portions including hori- Zontal ribs 36,adapted as the cutter rides between adjacent ends of neighboring ironsto engage the edges of said irons and compel by the pressure on theblade portions an effective operation of said blade portions with theadjacent edges of such irons.

Secured to the delivery end of the machine and projecting beyond thesame is an auxiliary frame 37 including channel bars 3S arranged inspaced parallel relation with channel portions disposed in proximatearrangement. The inner `ends of the bars are connected to the main frame1 through a cross piece 3S and the outer end supported upon uprights 39,the frame being arranged in horizontal alinement with the lower path oftravel of the irons. Mounted for sliding movement in this frame is a U-shaped carrier L10 constituting a longitudinal cutter. rhe inner ends,that is the ends adjacent the main frame, are beveled or inclined inboth the horizontal and vertical directions, the vertical inclinationbeing downwardly and forwardly and thc horizontal inclination beingoutwardly and forwardly. @n such inclined ends are arranged cutters 1-1comprising approximately Y- shaped members having their ends #vl-2sharpened to provide cutting edges, the reduced portion of the membersbeing longitiulinally slotted at to engage pins -i--ithreaded into theends of the frame bars. The corners of the cutters A11 are rounded, asshown, in order to avoid ineifectiveness of such cutters through contactbetween the cutters and the ends of the plates as the cutters move intooperative position. rlhe cutters project toward each other, and in theouter surface of each frame bar there is formed a recess 4-5 for thereception of leaf spring i6 which bears against the end of the cuttersso as to normally maintain them in proper position, while permittingyielding outwardly to accommodate themselves to irregular' formation orposition of the particular iron on which they are operating. The crossbar of the frame 40 is connected by a bracket 47 to the bar Li8 which inturn is connected to the curved end of the arm 10, so that in the sweepof said arm 10 the longitudinal cutter frame 40 is reciprocated. j

Beweisen-Supported in plates 49 rising from the frame bars 38 is a shaft50 on which isv secured spaced parallel receiving lingers 51.V The'fingers are connected for simultaneous movement through theirattachment to the shaft and are each construct-- eel-of inner and outersections '52,- 53, the

outer section lbeing pivotally connected. to the inner section andhaving its lower or rear edge inclined and bearing against acorrespondingly inclined shoulder on the inner section as at 54, Fig.13, the arrangement of the inclination permitting a swinging movement ofthe outer sections with re lation to the inner sections in one directionwhile `preventing it in the opposite direction. Springs 55 are connectedto maintain a normal or alined position of the sections. The lingers areprovided with a transverse shelf 56 having an outwardly extending lip 57forming a stop :tor the lower edge of the received cake as will laterappear.

The receiver ingers are positively oper ated in reverse directions, thefingers being moved into receiving position through the medium of thearm 58 secured upon one end of the shaft 50 and having an outerpivotally connected section 59 adapted to break in one direction andnormally held in alinement with the main section by a spring 60. rl`hearm 58 is operated through the medium of a roller (il mounted on thelower end of the strip '62 depending from the inner edge of one of thearms oit the cutter frame 40, the lower ledge of thc channel portion ofthe iixed frame 38 receiving such frame portion 40 being cut awav topermit movement of the strip without interference. There is alsoprovided a means i'or operating the receiving lingers toward thereceiving tray to be later described` such means comprising a groovedroller 63 fixed upon the shaft 50 and a coiled extension spring 64terminally iixed to the roller and to a bracket 65 secured to the rearor outer portion of the uprights 39, as shown. As the frame Li0reciprocates, the receiving fingers are operated, the movement of theframe toward the machine proper causing the roller 61 to pass the arm58, slightly displacing the section 59 to permit this result. As theframe moves in the opposite direction, the roller engages the arm androcks the sha't't to move the fingers into cooperation with theparticular iron, as will later appear. A stop 58 is provided againstwhich the arm 58'contacts to prevent the receiver fingers from cuttingtoo far backward and thereby avoid possibility of crush ing or breakingthe successive cakes deposited in the receiver.

. rlhe receiver proper comprises a platform or sheet 65 secured at thelower end to opposing guides 6G which are formed to cooperate with achannel frame portion 38 so as to slide thereon. The platform 65 isinclined upwardly and rearwardly and braced by a section G7. Theplatform which is approximately of a width corresponding to that betweenthe side bars of the trame 38 is formed with supporting lingers 68,projecting at anv appropriate angle thereto near the lower end,

edge of the cakes. As the receiver proper is designed to accommodate anumber of cakes, means must be provided whereby said receiver will begradually moved rearwardly as successive cakes are deposited. To'securethisresult, I mount upon thegrooved pulley 63 a holder in the form of adisk like member. 69 having a reduced shouldered portion 70, the diskmember 69 being formed with a slot 71 to encircle the shaft 50 and 'witha series ot' slots72 to receive screws 73, whereby the disk member issecured to one surface of the pulley 63, while permitting an adjustmentas desired. A band74 encircles the shoulder of the Vdisk member restingbetween the disk and the grooved pulley, the position ol the disk 69 onthe grooved pulley constituting the band 74 as an eccentric strap. Anarm 75 extends rigidly from such eccentric strap, the lower edge ofwhich is formed with a series of teeth 76 projecting in the' rearwarddirection, that is toward the receiver proper. T he receiver is formedwith an opening 7 7 through which the spring 64 passes, onel edge of theopening having a toothed plate 78 with which the teeth 7 6 cooperate.From this description, it will be obvious that a step for step movementwill be imparted to the receiver proper, in each actuation of thereceiving fingers whereby compensation is made for the thickness of thesuccessive cakes as they are deposited on the receiver.

The respective cutters are automatically operated by the travel of theirons, and the means whereby this is accomplished is illustratedparticularly in Figs. 6, 7, and 8. Projecting from one of the uprights,as 7, is a plate 79 on which near what may be termed its outer edge, issecured a block 80 having a il-shaped extension 81 to overlie and forman abutment on the plate 79. A plate 82 is adjustably secured upon theplate 79 in advance of the'abutment 80, said plate 82 having a similarV-shapcd projection 83 extending toward the abutment 8l and forming acorresponding abutment above the surface of the plate 7 9. On the bottomof each iron, at an appropriate point, is secured a block 8lin which isslidably mounted an actuating member comprising a bar 85 havingdepending therefrom through a slot in the plate spaced lugs 86 and 87.The bar 85 extends beyond the plate and is provided with a dependingstem having a roller 88 secured thereon. The lugs 86 and 87 are designedto coperate with and respectively operate the levers 11 and l2, theroller 88 being designed to shift the bar 85 through engagement with theabutments 8l and 83.A

Assuming the parts', constructed and- Vranged as described,'it will beVobvious that, as an ironwith the contained ,material-apa preaches the`improved cutting mechafnisin,` there@ 'Will here. been peaked. as ailllater appear, -it will be understoodzthat the lug 86 -is normally inposition to engagefthe lever `1.1. As vthe iron advances, "this lugthrough its enga-gement ,with fthe'lever, will through :the arm 19,.section 20,'gear y21,

and :pinion 9, rock thefshaft 8. This, from the 4previously .describedstructure, operates the transverse cutter, the .longitudinal `cut` ters,and positions the vroller 61 :in advance ther advance ofthe `ironoperates the lever 12 to reverse `the movement just described, returningthe cutters to normal position. Immediately Asucceeding such operationof the lever 12, the roller 88 cooperates with the abutment 83 shiftingthe lug 87 laterally of the Ylever 12 and returning the block 85 tonormal position, which is that tihe ylug 86 is so arranged that Ait willengage Vthe lever 1 1 in the next cooperation ofthe particular irontherewith. In `the return of the longitudinal rimmer frame l0, theroller 61 engages Ythe arm 5S and forces the receiving lingers'into aposition to cooperate YWith the iron just being opened to discharge thecake.l

As the fingers ride into receiving position, the respective sectionsthereof Will Vbreak to permit fthe free end of the outer section to ridebeneath the iron until it occupies a position Vshovvn in F ig. 1. Therelease of the lingers from the carried cake causes the spring 64 toreturn the fingers to normal position, delivering the cake to thereceiving tray.

From the above description, it will be obvious that the improved machineautomatically trims both sides and ends of the iron, so as to removeeXcess material and that a resultant product presents cakes of uniformsize and eliminates the necessity of an attendant hereinbefore referredto, required for the hand trimming Vto gain this result.
